(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The Oslo area has a rich geodiversity, a long history of scientific investigations, and several protected geosites. Many of the protected geosites were protected some 30 years ago and have until recently not been followed ...

Provenance of quartz grains from soils over Quaternary terraces along the Guadalquivir River, Spain (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The characterisation of quartz grains’ chemical and mineralogical properties in sediments and sedimentary rocks is widely used in provenance studies. This paper analyses quartz grains from the coarse sand fraction in soils ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)In the present study, we describe the new species, Psora altotibetica, from nine localities in China (Tibetan area) and Nepal. The study includes analyses of anatomy, secondary chemistry, and DNA sequence data of P. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Herein we describe the new species, Psora taurensis, from two localities in the Taurus Mountains in Turkey at ca. 1000 m altitude. Investigations of anatomy, secondary chemistry and DNA sequences (ITS and mtSSU) of P. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Estimating time-dependent rates of speciation and extinction from dated phylogenetic trees of extant species (timetrees), and determining how and why they vary, is key to understanding how ecological and ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Pegmatites are extremely coarse-grained and heterogeneous rocks in which quantitative measurements of mineral proportions and chemical compositions of the whole rock are virtually impossible to acquire. Thus, conventional ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Aim Many thematic land cover maps, such as maps of vegetation types, are based on field inventories. Studies show inconsistencies among field workers in such maps, explained by inter-observer variation in classification ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Legally protected plants are illegally traded through online sales platforms and orchids are a significant component of this wildlife trade. This study focused on salep, a compound product made from wild collected orchid ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Quartz from 254 pegmatites representing eight pegmatite fields and provinces worldwide was investigated by laser-ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) to determine concentrations of trace elements ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Populations of large mammals have declined at alarming rates, especially in areas with intensified land use where species can only persist in small habitat fragments. To support conservation planning, we developed habitat ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)To determine the present-day community composition of siliceous Rhizaria (Radiolaria and Phaeodaria) in Norwegian fjords, plankton tows were conducted in south-western and northern Norwegian fjords in September 2016. The ...

Range contraction and increasing isolation of a polar bear subpopulation in an era of sea ice loss (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Climate change is expected to result in range shifts and habitat fragmentation for many species. In the Arctic, loss of sea ice will reduce barriers to dispersal or eliminate movement corridors, resulting in increased ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Gene expression changes potentially play an important role in adaptive evolution under human‐induced selection pressures, but this has been challenging to demonstrate in natural populations. Fishing exhibits strong selection ...
